Worship versus Everlasting Torment

[Maveric78f]

How do these 2 cards interact?

In other words, is worship a prevention effect, or replacement effect that is not involved by the Everlasting Torment's effect?

Everlasting Torment
Players can't gain life.
Damage can't be prevented.
All damage is dealt as though its source had wither. (A source with wither deals damage to creatures in the form of -1/-1 counters.)

Worship
If you control a creature, damage that would reduce your life total to less than 1 reduces it to 1 instead.

If we look at at Everlasting torment it gives us not replacement effects, but rather rules for things. Worship gives us a replacement effect. It's basically telling us, "Whenever a source would damage you to below one life, instead replace that amount of damage with an amount of damage that only reduces it to 1 instead."

So, since Worship never actually gains you life (Because you don't drop below 1 then gain), the first part of Everlasting torment doesn't matter. Worship does not say "Prevent extra damage that would reduce your life total to less than one," so the second part of Everlasting Torment doesn't matter either. Thirdly, wither has no effect on worship (Obviously).
